I just added the special-case check so that now single-item assignment
works as expected
for object arrays. It's in SVN.
It's still ambiguous as to what to do with initialization from container
array([[1,2,3],[3,4,5]],'O') produces an 2x3 array of integer objects.
Or did you want a 1x2 array of list objects?
Not sure how to fix that one without a special-purpose object array
creation function that fixes the shape.
